A
quick fix for most communication errors can be achieved by resetting the printer
and/or rebooting the PC. Simply disconnect the printer from your computer.
Reboot your pc. Unplug and re-plug the printer into the power source to reset
it. When the printer turns on, reconnect it to your computer. Then try to print
again once the computer fully recognizes the USB connection.

If
that doesn't help, try the steps below:

1.
Disconnect the printer from your computer.

2.
Unplug and re-plug the printer into the power source to reset it.

2.
On your computer, go to Control Panel > Printers and Faxes.

Delete the Lexmark print object.

Panel > Printers and Faxes. If you see a new Lexmark print object in the

Go to Control Panel/Printers. Right click on your printer's name, and hit Print Test Page. If printer prints a page out, then the problem is likely with the software you're using to print - make sure you have selected the right printer in the dropdown. If the printer's name doesn't show in the Printers folder of Control Panel, the driver for it has not been installed. Do so and try again.

The requires to be programed to attain the new accessories installed. Usually the printer would continue functionality once depleted supplies have been replaced. However, power off the entire computer and peripherals, disconnect every link allow to rest for some moments, reconnect the entire setup. Once powered on the new setup should be recognised.

pls u check the fiery and dc12 printer cable. if u have another cable pls replace and chek that also. i think the problem is in only the connectres. u remove and clean all conctres and refix. maybe the problem solved.

I think you may just need to live with this. That is, I don't have a solution, but printing is not affected. The guy who refills my cartridges says it is because the Pixma only recognises new Canon filled cartridges once. After that, the printer has no way of recognising them. Annoying, I know. Love the 150, but it throws up mysterios messages at times. Often, turning the printer off, waiting 60 seconds and turning it back on will do the trick. If this fails (more annoying), shutting down the computer and the priinter and starting again can get the printer working again.
Good luck
